pertains to make and usethe same, reference y being had tothe accompanyin drawings, which form a part of this speci `cation.

My invention relates to motor vehicles, and an object of my improvements is to provide an improved Wheel mounting in connection With means for driving the Wheel. accomplish this object in the device shown in the accompanying drawings, in Which,-

Figure l, is a plan view of the rear portion of the chassis of an automobile showing a part of the driving mechanism. Fig. 2, is a side vieu7 of the same. Fig. 3, is a horizontal section of the wheel and Y adjacent parts. Fig. 4, is a detail sectional view on the line 4.-l of Fig. 3, looking from beneath said ligure. Fig. 5, is a view similar to Fig. 3, except that the parts of the Wheel mount ing are separated. Fig. 6., shows a. modified construction, the section being in a-plane at right angles to that upon which the section oi Figs. 3 and 5 are taken. Fig. 7, is a detail section taken on the line re-"7 of Fig. l.

A, A, indicates the side pieces kof the frame of the chassis; B, is the rear axle; C, C, are Wheels adapted to turn upon the axle Bf. Y

mounting for the gears and inclosure there- .for and for brake mounting and for attaching the 4torque resisting members. This plate H isprovided'with a hub Hl'slotted toward its inner end, as indicated at It and provided with ears 11,1 through which a bolt may be Passed by which bolt the parts of the hub H may be'dravvn together to clamp an inclosed'object.

Bre' land Bre are respectively interior and exterior brake straps. These straps are mounted on the plate H and are controlled in the'usual Way by levers, and spindles in bearing Br?) on the plate H.

l, is aball bearing upon the axle B, keyed to prevent relative rotation by a key K, but adipted to move longitudinally on said ax e.

l1, is the inner annulus or race'of the ball bea-ring I; this annulus is provided With screw threads z at its inner end.

The axle B passes through the hub H?. There is a sleeve J surrounding the axle l?- and tting Within the huh H1 of the plate H. The sleeve .l is provided With internal screw threads at its outer end which engage the screeT threads i on the annulus l1.

J1, is a head upon the sleeve J adapted to be grasped by a Spanner Wrench. The head J1 abuts against the inner end of the hub H1 of the plate H.

L, is a beveled gear wheel having a hub L1 which passes over the ball bearing l1 and having a shoulder .fr abutting against the N, is a nut upon screw threads at the outer end' of .the axle B bearing against the Washer n and holding the bearing M in v place.

The hub C1 of the Wheel C extends over Ithe bearing M.

' inner edge comes adjacent to the hub L1 of face abuts against the inner face of the outer portion of the ball bearing M. By the annulus R and the outer inturned end of `the hubC1 engaging the outer annulus oi' the ball bearing M, the hub is held in position. Ball bearing M is adapted to resist thrust in both directions.

P, is a sheet metal plate dished out into theiorm shown in cross section in Figs. 3 an 5, its outer edge being secured to the inner surface of the plate H, by bolts y).

The plate extends over the beveled gear Wheel L and extends inward so that its L1 of the geary L.

Lubrication may be placed and will be retained lbetween the plates P and II and within the drum w, the latter preventing the lubrication from adhering to the hub L1.

E1, is a driving shaft. E2, is a ball bearing for the shaft El. E3,

is a beveled gear wheel or pinion upon the end of saidshat, its teeth engaging the teeth of the beveled gear wheel L (Fig. 3). The shaft Elbears in a bracket Il?v forming apart of the stationary plate H;

C2, is an annular plate secured by the bolts g, g, to the inclosed end of the brake drum G and to wheel C.

The annulus C2 is provided with a. boss c which extends inl ward and surrounds the hub C1 of the wheel C. The boss c is provided with slots c1 extending parallel to its axis from its inner end and from the inner surface or' the hub.

L2, (Fig. 5) are teeth adapted to lit in the slots in the boss c to form an engage men-tbetween the Vboss c and the huh L1 of.

'the gear wheel L.

By turning the sleeve J by a Spanner wrench engaging its head J1, the position of the bearing I may be adjusted longitudi nally of the axle B relative to the plate II .and thereby the relative positions of the gear wheels E3 and L may be adjusted.

To remove the wheel, all that is necessary` is to takeoii' the nut N and washer n, when the wheel maybe drawn directly from the axle carrying the bearing M with it.- The thrust of the gear wheel E3 pressesthe gear wheel L against the inner end of the bearing I.

While I contemplate using conical llears, I have shown a worm and gear wheel which may be used as well, as indicated in Fig. 6, in which ESG. is the worm and La the worm incassa wheel. I"lhe other construction is entirely similar to that above described except that I provide friction washers v/ betweenfthe hub L3 of the worm wheel La and the plate H where the worin is used, to take the thrust of the worin when theicar is being driven backward.

In Fig. 7 I have indicated a construction that may be used when radius rods D, D, are used. rlhis construction is intended to secure some degree of flexibility in the tubes E, E. A slip joint for instance, is provided at c (Fig. 7) .and a universal joint f is interposed in the shaft, two parts of which therefore may have relative longitudinal movement to a limited extent. There are also provided at .e the bearings usually used in worm gearing.

The ball bearings I and M are radial and thrust bearings.

It will be noted that in the above con struction, the wheel may have an end motion relative tothe axle without disturbing the accurate mesh of the driving gears and that a simple means|for adjusting the mesh of the gears without disassembling the parts is provided. It will also be noted thatthere is a means forquickly and easily removing the driving wheel from the axle without disturbing the gears, their mountings, or their protective casings.

lt will be noticed that in my other application above referred to, I use the tubes E, E, as torque members while in the present construction, I have provided special separate torque members to take the various strains and have constructed the tubes and shafts with certain degree of flexibility.

It will be noticed that all the driving parts are mounted `on the plate H, which may have a slight movement longitudinally of the axle. The teeth L2 by which the driving wheel C is engaged to drive the same are freely removable by movement in the direction of the length or' the axle. The

position of the gear wheel L may be adjusted .relative to the gear wheel E3, while both gear wheels .are secured to the plate lil.

The plate H is so mounted upon the axle that it may rotate relative thereto. There-y fore the plates H and P combine to form a casing which loats upon the axle.

What I claim 'is 1. In a motor vehicle, the combination of a driving wheel rotatably mounted on said vehicle, a gear wheel coaxial with said driving wheel, means for engaging said gear wheel and driving wheel so as to prevent relative angular motion and to permit motion in the direction of `their axis, a shaft and gear adapted to drive said gear wheel, said shaft being mounted in astationary bea-ring, and means for adjusting the position ofthe first mentionedgear wheel relative to the driving wheel, the relative posij neonates movement of the first mentioned gear vvheel .relative to the driving Wheel shall adjust the mesh of said-gear Wheels."
